Abstract:The nanoscale directed assembly of nanoparticles has a many applications in biotechnology, energy, electronics and nanomaterials. Directed assembly of nanoparticles for biosensor devices, nanowire and interconnects are being conducted at the CHN. The nanoparticle based biosensor is used for the detection of multiple cancers and targeted drug delivery. The sensors require assembly of nanoparticles in specific predetermined locations. Electrophoresis is one of the promising methods for assembling these nanoparticles because of its speed. In order to obtain reliable assembly, it is important to understand the assembly mechanism and the governing process parameters. In this study, we have done investigated applied voltage, time of assembly, pH and conductance of the solution. The results show that the control of the assembly process enables precise and repeatable assembly of 50 nm PSL nanoparticles over large scale at high rate which is crucial for many applications
